Is it o.k. to use some Sweet PDZ in shavings on the coop floor. The floor is 6x12 feet with 18 pullets. Under the shavings is about 4 inches of 1 inch gravel and heavy clay soil under that. It's always pretty dry in there(as we get NO rain at all lately). My concern was this winter there will be snow and it usually melts quickly and the ground will be soggy for quite awhile. I thought using some Sweet PDZ would help control moisture in the coop in between cleanings. Any thoughts????
